Celebrate more often: you've got a place on the planet, the one consistently rated the best in the known universe. Don't let a day go by without remembering that. That irritating e-mail is just a tiny grain of sand in the enormity of it all.
Thoughts come and go. Choose the best ones.You do not need to be your crappy thoughts.
Hang out with people you want to hang out with. They enliven, they encourage and they get it.
Visit Earth's greatest edges where you (re-)realise the specialness of it all: sea-shores, mountains and the desert are great places to start.
Write every day until you expunge your demons.
Become self-reliant: it makes things a damn sight easier.
Get away from light pollution, look up and (re-)learn a constellation or two. Remember: Man's an explorer and has sailed to the edge of the planet, written sagas and stepped on the Moon. You too: go beyond the mall.
Phone your mum/mom regularly.
Walk bare-foot. Yeah, a bit hippieish (official spelling) but you do feel very grounded. And your toes will spread and love it.
Have a plan to do a job you want to do. One where you are achieving mastery, you are feeling good and breaking the limiting equation, time=money and replacing with the empowering equation, value=money; then you can make what you need without working 24 by 7.
